Schedule

  1. 相关属性设置

    • 扩展属性方式

      var host = Host.CreateDefaultBuilder()
          .ConfigureServices(services => 
          {
              services.AddQuartz(opt => 
              {
              	// 主键
                  opt.SchedulerId = "";
                  // 调度名称
                  opt.SchedulerName = "";
                  // 最大并发(一次运行Job的最大数)
                  opt.MaxBatchSize = "";
                  // 可中断作业
                  opt.InterruptJobsOnShutdown = true;
                  // 关机时中断作业可等待
                  opt.InterruptJobsOnShutdownWithWait = true;
                  // 批量设置触发器的执行的提前时间
                  q.BatchTriggerAcquisitionFireAheadTimeWindow = TimeSpan.Zero;
              });
          })
          .Build();
      
    • 手动实例化

      var scheduler = ScheduleBuilder().Create()
          .WithMisfireThreshold(TimeSpan.FromDays(1))
          .WithId("")
          .WithName("")
          .WithMaxBatchSize(2)
          .WithInterruptJobsOnShutdown(true)
          .WithInterruptJobsOnShutdownWithWait(true)
      	// 提前1分钟进行批量执行	    				.WithBatchTriggerAcquisitionFireAheadTimeWindow(TimeSpan.FromMilliseconds(1))
          .Build();
      
  2. StdSchedulerFactory

    默认使用的调度工厂,相关配置文件存储在本地进行加载。

  3. DirectSchedulerFactory

    不建议使用,除非:对于Quartz.NET很熟悉并且所有配置项都能通过代码进行配置

  4. Loggin

    • 从3.1开始,可以通过配置Microsoft.Extensions.Logging.Abstractions来代替 LibLog library

    • 实例化配置

      // obtain your logger factory, for example from IServiceProvider
      ILoggerFactory loggerFactory = ...;
      
      // Quartz 3.1
      Quartz.LogContext.SetCurrentLogProvider(loggerFactory);
      
      // Quartz 3.2 onwards
      Quartz.Logging.LogContext.SetCurrentLogProvider(loggerFactory);
      
    • 使用Microsoft DI 集成进行配置

      services.AddQuartz(q =>
      {
          // this automatically registers the Microsoft Logging
      });
      

Clustering

  • 集群配置,仅适用于JobStore设置为JobStoreTX时

  • 如果IJobDetail中RequestRecovery设置为true,负载均衡和作业故障转移会被启用

  • 通过配置 quartz.jobStore.clustered=true来启用集群模式,集群中每个实例都有相同的副本

    • 每个节点必须有一个唯一的instanceId(quartz.scheduler.instanceId)

    注:

    1.单独的机器不要运行集群,

    2.同一个数据库不能在集群启动后在链接一个非集群的实例

    3.如果某个节点CPU到达了100%时,请优化它,不然会存在丢失作业的风险

配置资源

​ 默认情况下,StdSchedulerFactory会从当前工作目录中加载quartz.config文件,如果失败,则会加载quartz.dll中的配置文件。非默认情况下可通过修改quartz.properties进行文件设置

​ 可使用以下四种方式进行配置信息

  1. 通过Initialize或StdSchedulerFactory方法修改

    // 创建Collection
    System.Collections.Specialized.NameValueCollection collection = new System.Collections.Specialized.NameValueCollection();
    // 新增key和value
    collection.Add("quartz.threadPool.ThreadCount","20"); 
    // 实例化调度工厂
    var factory= new StdSchedulerFactory(collection);
    // 也可以通过factory.Initialize(NameValueCollection)来初始化
    // Initialize必须在GetScheduler方法之前
    factory.Initialize(collection);
    // 获得调度实例
    var scheduler= await factory.GetScheduler();
    
  2. App.config配置

    .net Framework生效

    <?xml version="1.0" encoding="utf-8" ?>
    <configuration>
        <configSections>
            <section name="quartz" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
        </configSections>
    
        <quartz>
            <add key="quartz.threadPool.ThreadCount" value="11"/>
        </quartz>
        <startup>
            <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
        </startup>
    </configuration>
    
  3. quartz.config配置

  4. Enviroment(环境变量配置)

    // 设置环境变量
    Environment.SetEnvironmentVariable("quartz.threadPool.ThreadCount","50");
    System.Collections.Specialized.NameValueCollection collection = new System.Collections.Specialized.NameValueCollection();
    var factory = new StdSchedulerFactory();
    var scheduler= await factory.GetScheduler();
    
主要配置项
配置项名称 Required 类型 默认值 说明
quartz.scheduler.instanceName no string 'QuartzScheduler' 客户端/集群:区分调度器
quartz.scheduler.instanceId no string 'NON_CLUSTERED' 唯一键
AUTO:自动生成
SYS_PROP:系统属性生成
quartz.scheduler.instanceIdGenerator.type no string Quartz.Simpl.SimpleInstanceIdGenerator, Quartz instanceId设置为AUTO时生效
quartz.scheduler.threadName no string instanceName + '_QuartzSchedulerThread' 调度线程名称
quartz.scheduler.makeSchedulerThreadDaemon no boolean false 是否为守护线程

quartz.scheduler.batchTriggerAcquisitionMaxCount no int 1 集群使用,当前节点最大触发数
quartz.scheduler.batchTriggerAcquisitionFireAheadTimeWindow no long 0 在计划触发之前可以获取几个触发器,数量越大越不精确触发
线程池配置项
Property Name Required Type Default Value 说明
quartz.threadPool.type no string Quartz.Simpl.DefaultThreadPool, Quartz 线程池类型
quartz.threadPool.maxConcurrency no int 10 最大并发数

自定义线程池

/*
 系统自带
 DedicatedThreadPool		自定义了线程池(声明了专用的线程池)
 TaskSchedulingThreadPool	使用TaskScheduler调度任务
 ZeroSizeThreadPool			零大小线程池
*/
// MyLibrary为dll名称
// MyLibrary.FooThreadPool 命名空间+类名
quartz.threadPool.type = MyLibrary.FooThreadPool, MyLibrary
// 未给出说明
quartz.threadPool.somePropOfFooThreadPool = someValue
监听配置项

可以由StdSchedulerFactory实例化和配置

// MyListenerType必须有无参构造函数
//触发器注册监听(全局)
// 空间+类型, dll名称
quartz.triggerListener.NAME.type = MyLibrary.MyListenerType, MyLibrary
// 属性名称
quartz.triggerListener.NAME.propName = propValue
// 属性名称
quartz.triggerListener.NAME.prop2Name = prop2Value
// 作业注册监听(全局)
quartz.jobListener.NAME.type = MyLibrary.MyListenerType, MyLibrary
quartz.jobListener.NAME.propName = propValue
quartz.jobListener.NAME.prop2Name = prop2Value
插件配置项

与监听类似,配置一个插件,插件类型必须有无参构造函数

quartz.plugin.NAME.type = MyLibrary.MyPluginType, MyLibrary
quartz.plugin.NAME.propName = propValue
quartz.plugin.NAME.prop2Name = prop2Value
  • 日志记录触发器历史插件

    // 引用插件,需要有Quartz.Plugins.dll文件
    quartz.plugin.triggHistory.type = Quartz.Plugin.History.LoggingTriggerHistoryPlugin, Quartz.Plugins
    // 启动信息
    quartz.plugin.triggHistory.triggerFiredMessage = Trigger {1}.{0} fired job {6}.{5} at: {4:HH:mm:ss MM/dd/yyyy}
    // 完成信息
    quartz.plugin.triggHistory.triggerCompleteMessage = Trigger {1}.{0} completed firing job {6}.{5} at {4:HH:mm:ss MM/dd/yyyy} with resulting trigger instruction code: {9}
    
  • XML调度数据处理器插件

    作业初始化插件从XML文件中读取一组作业和触发器,并在初始化期间将它们添加到调度程序中;它还可以删除现有数据。

    quartz.plugin.jobInitializer.type = Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin, Quartz.Plugins
    // 读取的文件路径
    quartz.plugin.jobInitializer.fileNames = data/my_job_data.xml
    // 未找到报错
    quartz.plugin.jobInitializer.failOnFileNotFound = true
    
  • 关机钩子插件

    捕获CLR终止的事件,并在调度程序上调用shutdown

    quartz.plugin.shutdownhook.type = Quartz.Plugin.Management.ShutdownHookPlugin, Quartz.Plugins
    quartz.plugin.shutdownhook.cleanShutdown = true
    
  • 作业中断监视器插件

    捕获作业长时间运行(超过配置的最大时间)的事件,并告诉调度程序在启用时“尝试”中断它。插件默认为5分钟后发出信号中断,但默认的defaultMaxRunTime配置为不同的值,配置值以毫秒为单位。

    quartz.plugin.jobAutoInterrupt.type = Quartz.Plugin.Interrupt.JobInterruptMonitorPlugin, Quartz.Plugins
    quartz.plugin.jobAutoInterrupt.defaultMaxRunTime = 3000000
